Getting more speed from your mower.

              This is a fairly simple task when you break the idea down to its bare bones.There is a pulley on the engine drive shaft and a pulley on the transaxle.If you increase the diameter of the pulley on the engine or decrease the size of the pulley on the transaxle you would increase speed.

as you can see in this crudely drawn picture,the larger engine pully coupled with a smaller rear end pully will get you to higher speeds.Unfortunately this will only work to a certain extent.If you use too large of a pulley on the engine and to small of a pulley on the rear end,then the engine will lose torque and could cause you to have to be pushed to even move out of your tracks.

There is a balance to be found with this project,acheiving higher speeds without losing too much torque or ruining the gears in your rear end.I come from the school of thought "use what you got" so just tinker with it.if you don't get the results you want,trade around for more parts or if necessary buy the part you need ( I never have a problem trading for parts)
